Connect and Protect: Benefits of Perimodiolar

Please note: exam questions are subject to change.

1. What are the two primary design goals of the Slim Modiolar electrode? Improve battery life and reduce costs Connect to the hearing nerve and protect the cochlea Increase data logging and improve programming speed Increase insertion depth and maximize electrode length
2. Why are perimodiolar electrodes designed to sit closer to the spiral ganglion cells? To increase cochlear coverage by extending deeper into the cochlea To allow for larger electrode contacts To provide more focused and efficient stimulation To eliminate the need for programming adjustments
3. In the study comparing electrode discrimination success, what percentage of success was reported for perimodiolar placement? 42% 47% 66% 77%
4. In the University of Utah intra-patient comparison study, what was the median CNC word score reported for perimodiolar electrodes? 42% 57% 66% 75%
5. How might electrode type/placement impact device programming? Lower stimulation means more headroom for compliance limits, more mapping flexibility Lower stimulation means less headroom for compliance limits, less mapping flexibility Higher stimulation means more headroom for compliance limits, less mapping flexibility Higher stimulation means more headroom for compliance limits, more mapping flexibility
